In this episode of Talking Tech, we sit down with Ori Lempel, Senior Principal Engineer in the P-core architecture team, who explains the goals that drove the design of Lunar Lake’s new Performance-cores. Codenamed Lion Cove, this P-core microarchitecture features significant changes from its Redwood Cove predecessor, including improvements to the fetch and decode pipelines, a completely revamped memory subsystem and, critically, the removal of Hyper-Threading logic.
